Lung cancer is an epidemical disease, annually there are 1.4 million deaths and about 1.6 million new cases.
More people die of lung cancer than of colon, breast, and prostate cancers combined.
Lung cancer mainly occurs in older people. About 2 out of 3 people diagnosed with lung cancer are older than 65.
Fewer than 3% of all cases are found in people under the age of 45. The average age at the time of diagnosis is about 71.
The chance that a man will develop lung cancer is about 1 in 13, for a woman, the risk is about 1 in 16, These numbers include both smokers and non-smokers. For smokers the risk is much higher, while for non-smokers the risk is lower.
Lung cancer incidence rates were around twice as high in more developed countries compared with less developed countries

LUNG CANCER
STATICAL IN THE
WORLDE
4. LUNG CANCER IN THE ARAB
WORLD
15/22 (68.1%) of the Arab countries have lung
cancer as one of the most frequent five types of
cancer, for both sexes.
In 2008 about 9,537 new cases was reported in
ages below 65 for both sexes, and 7,059 cases for
ages above 65.
Lung cancer are about 15 fold higher in Tunisia
than in Sudan for men, and about 10 fold higher in
Bahrain than in Yemen for females.
5. In 2020 there is expected to be 14,788 new lung cancer
cases in the Arab countries for ages below 65, and 14,788
cases for ages above 65 in both males and females.
By the year 2025, 85% of the world’s smokers will live in
less developed countries.
It is estimated that by 2030 lung cancer will be the sixth
most common cause of death, compared with its current
ranking of ninth.
By 2030 it is expected that around 70% of all tobacco-
related deaths (including lung cancer) will occur in the
world’s poor and middle income nations, compared with
the current estimate of 50%.31,109.

LUNG CANCER IN THE
FUTURE
6. .Lung cancer have 2 major types
Non-small cell lung
cancer
small cell lung
cancer
7. .
Squamous cell (epidermoid) carcinoma:
About 25% to 30% of all lung cancers
It start in early versions of squamous cells, which
are flat cells that line the inside of the airways in the
lungs.
It often linked to a history of smoking
It found in the middle of the lungs, near a bronchus
Adenocarcinoma:
About 40% of lung cancers
Start in early versions of the cells that would normally secrete
substances such as mucus.
Occurs mainly in people who smoke (or have smoked), it is also
the most common type of lung cancer seen in non-smokers.
It is more common in women than in men
It is more likely to occur in younger people than other types of
lung cancer.
Non-small cell lung
cancer
8. .
Named for the small cells that make up these cancers.
SCLC often starts in the bronchi near the center of the
chest.
It tends to spread widely through the body fairly early in the
course of the disease.
The cancer cells can multiply quickly and spread to lymph
nodes and other organs, such as the bones, brain, adrenal
glands, and liver.
Sometimes the areas of cancer spread are seen as large
tumors on x-rays and other imaging tests, but early on
these areas may not be visible.
SCLC spreads early, so removing the tumor in the lung
rarely cures the cancer. This is why surgery is rarely used
to treat SCLC . On the other hand, chemotherapy, which
can reach cancer cells throughout the body, is the main
treatment for small cell lung cancers.

11. T
N
M
The TNM staging
system
Indicates the size of the main (primary) tumor
and whether it has grown into nearby areas.
Describes the spread of cancer to nearby
(regional) lymph nodes. Cancers often
spread to the lymph nodes before going
to other parts of the body.
Indicates whether the cancer has spread
(metastasized) to other organs of the body.
)The most common sites are the brain,
bones, adrenal glands, liver, kidneys, and the
other lung.)
M: Metastasis
T: Tumor
N: Lymph nodes
12. Cancer cells are seen in a sample of
sputum or other lung fluids, but the
cancer isn't found with other tests, so
its location can't be determined.

across
It has not reached the membranes
that surround the lungs
It does not affect the main
branches of the bronchi.
It has not spread to lymph nodes
or distant sites
The main tumor is between 3 and

It has grown into a main
bronchus , the visceral pleura ,and

Chemo (sometimes along with radiation

tumor

This is known as neoadjuvant therapy.
After surgery: to try to kill any cancer cells
that may have been left behind..This is
known as adjuvant therapy.
